Anyone else want to hear a non-diegetic song in MLP?

You know, a song that isn't sung by any characters onscreen, but rather by offscreen singers? (Think something like the Phil Collins songs in Disney's Tarzan, or most of the songs in Bambi.)

I'm surprised a musical series like MLP hasn't done this yet. The closest I can think of so far is "This Strange World" from the first Equestria Girls, but since Rebecca Shoichet was singing, it was obviously meant to be in Twilight's head.
